Fw: Re: Expected voltage reading K3 Display ? at full RF output.

[bhtoub]

Hi Cliff,

1.0 V sounds about right. This all depends upon the length of wire and
size.
Assuming this is a regulated supply (switching or linear) and rated for
your
radio voltage and current wise and you don't remote sense, then the total
length
and size will determine the voltage drop.  Good Luck

Subject: [Elecraft] Expected voltage reading K3 Display ? at full RF
output.

Just a general question, thought my new power supply was dropping voltage
on
TX but no it is rock solid, I get about 1V drop at full power CW on the
K3 Display. Is this normal,

I have already replaced the troublesome PA pins is there something else
that
would cause this.

Don't think the drop over the power lead would cause it

Any ideas appreciated,
Cliff VK2CCJ
